ECG measurement using BIOPAC system
Kotek, Lukáš ; Rozman, Jiří (referee) ; Balogh, Jaroslav (advisor)
The main aim of this bachelor project is to acquainted with BIOPAC system and with the theory of electrocardiography. After investigation of possibilities to retrieve analog and digital data as well as measurement of ECG signal was developed circuit enable to convert analog signals to digital and then export digital signal via USB to the PC. Developed circuit is based on integrated circuits ATmega8 a FT232RL. Visual Studio was used to create application for registration and calculation power spectrum ECG signal in C#.

Analysis of AVG signals
Janeček, David ; Balogh, Jaroslav (referee) ; Rozman, Jiří (advisor)
This semestral project deals with analytical arteriovelocitogram (AVG). In the first part I a question of collection data AVG curve. Doppler effect and principal of Doppler‘s systems whose assistance data gain is analyzed in this semestral project. In the next part I focus on methods of analytic signals AVG. This means discribing the curve, calculating coefficients or methods for correct evaluation of the signal. These analyzes should categorize the measured data into groups according to pathological changes, of which doctors will determine the next course of treatment. The final chapter deals with the method of cluster analysis to classify data measured by Doppler systems. I deal with the algorithm method and choose the best clustering procedure. In the following section I concern with the practical part. I describe the data which were provided, the program selected for the analysis and the description of the alghoritm. The last chapter describes the results I’ve obtained.

Device for measuring of the reaction time
Bohuš, Michal ; Kolářová, Jana (referee) ; Balogh, Jaroslav (advisor)
The aim of this bachelor thesis was become acquainted with human reaction time,its measurements and use. Part of the project was to build a device that measures reaction time of audio-visual stimulus. The device consists of stimulating and controlling parts. Audio-visual stimuli are scanned and controlled by microcontroler ATmega 16. Based on the obtained reaction time evaluate reaction time of measured entity.

X-ray beam hardening effect simulation
Šlof, Michael ; Balogh, Jaroslav (referee) ; Drastich, Aleš (advisor)
This bachelor thesis concerns itself with X-ray beam hardening effect simulation by filtering. The initial part introduces a theoretical background to the given topic. It is crucial to understand the underlying physical principles and laws prior to analysis so the X-ray radiation theory is introduced first. Units, quantities and an X-ray tube are also outlined as part of the X-ray theory. The practical part focuses on X-ray beam hardening effect simulation in programming language MATLAB. A strong emphasis is placed on parameter input, ease of operation and outcome analysis of the desired process as related to the X-ray beam hardening effect.

Dynamic plantography
Grossmann, David ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
This thesis contains introduction to the principles of dynamic plantography and it´s clinical application. Afterwards it is described feet anatomy, types of feet arch and human walking process. Next part describes principles of various types of tactile sensors and electrical platform Arduino. Most important part of this thesis is focused on teoretical design of device and it’s practical realization. The last part of diploma thesis is devoted to discussion of parameters of the device and to results of measuring of group of volunteers.

Peristaltic pump control via USB interface
Balogh, Jaroslav ; Chmelař, Milan (referee) ; Čech, Petr (advisor)
The purpose of this bachelor’s thesis is to practical realization of connection between peristaltic pump Rainin Dynamax RP-1 and PC, using USB interface. Integrated circuit device FT232R has been used in USB-RS422 converter, due to modified RS422 interface, which the pump RP-1 uses. There was also developed software for pump’s remote controll. RP-1’s functions can be driven from remote side or eventually automatized with this software. This work is based on semestral thesis and in future can be used in another aplications with RS422 or with RP-1 pump. Department of Biomedical Engineering, attached to FEEC, Brno University of Technology, will use this remote controll in analysis of DNA.

3D dental scanner
Kotek, Lukáš ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
The general aim of my master´s thesis is to study the actual principles of 3D scanning, the anatomy of human teeth, use of 3D scanning in dentistry and other medical fields. Another part of this thesis is about software and hardware design of 3D scanning system, which enable us to scan dental casts. This design is using webcam, projector and turntable. The principle of scanning is based on the activ triangulation. The output of 3D scanner is a horde of spots, which are used for reconstruction of a surface. The reconstructed surface is finally saved as .stl format.

Classification systems in the hospitals
Saliba, Walaa ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
Cílem této diplomové práce bylo nastudovat problematiku klasifikačních systémů v nemocnicích, které sledují především hospodářské požadavky hospitalizace. Následně bylo navrženo a naprogramováno webové rozhraní v prostředí Caché Server Pages (CSP), které poskytuje přístup k databázi CLINICOM. Pomocí webového rozhraní, je možno provádět klasifikaci pacientů do tříd MDC (Major Diagnostic Category), archivaci dat, výpočet DRG a další vybrané úkony. Webovou aplikaci by mohli využívat technicko-hospodářští pracovníci nemocnic a klinik jako jednoduchou pomůcku při své práci, respektive jako učební pomůcka biomedicínských oborů pří výuce zdravotnických informačních a klasifikačních systémů.

Position system design
Balogh, Jaroslav ; Čížek, Martin (referee) ; Čech, Petr (advisor)
The purpose of this diploma thesis was to explore possibilities, design and build 2D position system driven by PC via USB. ATmega16 and FT232R were used as the most important parts of hardware solution. Software for control of the position system was designed in C++ Builder and it can run under MS Windows XP. This work is based on semestral thesis and in future can be used in other applications or modified. 2D position system will be later used by UBMI in education and scientific applications.
